Application led May 16, 1914. Serial No. 838,97.

17 i) all 'whom it may concern Be it known that I, CLARENCE T. Roenes, a citizen of the United States of rmerica, and resident of the city of New York, in 'the county of New York and State of New York, have invented certain new and useful lmprovements in Door-Checks, of which the following is a speciiication.

rlhis invention relates to door-checks, and aims more particularly to provide a device adapted to be applicable to a one-way swinging door no matter how hung.

A further object of this invention is to provide a door-check adapted to operate by the passage of liquid through a restricted passa-ge which may if desired be in the nature of a lubricant and therefore substantially and thoroughly eliminate the working parts thereof; and an exceedingly important object thereof is to provide valve or baille means which are conveniently and practically7 adjustable and exceedingly elllcient in operation.

Another object of this invention is to provide a door-check adapted 'to be contained in one of the hinges of a door and to be operable by the other hinge.

Other objects and aims of this invention,

lore or less broao than those stated above, together with the advantages inherent, will be in part obvious and in part specifically referred to in the course of the following description of the elements, combinations and arrangements of parts and applications of principles constituting the invention; and the scope of protection contemplated will appear from the claims.

Referring now to the accompanying drawings which are to be taken as a part of thespeciication, and wherein is shown one of the various possible embodiments of this invention as at present preferred, an embodiment, it should prelim'inarily be noted, wherein the leaves of the hinge are designed to lie parallel with a single plane when the door hung thereon is in open position,

Figure l is an assembly view of the parts constituting said embodiment, in dooropen arrangement;

Fig. 2 is a perspective view of the sta tionary cylindrical cam piece and the rotatable key member therein.

Fig. (3 is a similar view of a further modified form of construction in which communication between the interior of the cam piece and the val ve, is through 'a bore or passage in the adjusting screw.

Fig. 6 is a perspective view showing in detail the adjusting screw employed in the form of construction illustrated in Fig. 6; and

Fig. 6b is a perspective view of a modified form of adjusting screw in which slot is provided along one side thereof.

Similar reference characters refer to similar parts throughout the several views of the drawings.

In Fig. l there is disclosed a hingeeleaf G including` an integral cylindrical shell 5, said shell having one end -closed by a plug 5e. The leaf 6 may be atliXed to a doorframe in the usual way, by means of holes 7 and a suitable plurality of coperant screws. Conical end-pieces 8 are integrally carried by leaf 9, which similarly to leaf 6 has holes l0 therein for cooperation with suitable screws whereby said leaf 9 may be mounted upon and support a door.

Reference now being had to Figs. 2 and 2, the cylindrical cam-piece ll is adapted to be lower bore 15a to produce an interior annular shoulder 16.

Fitting snugly within the cam-piece 11, but rotative relatively thereof is the member 17. rlhis member includes the main cylindrical portion 18 (shown in broken lines in Fig. 2,) a key-portion 19 of a cross section other than circular (here shown as square), an enlarged cylindrical portion 20, an eX- terior annular shoulder 20; and the crosshead blocks or wings 21 and 212L integrally carried by the portion 20. These wings 21 and 21a are preferably of rectangular crosssection and have their outer or end surfaces defining portions of the outer side Wall of a cylinder of the same diameter as that of the outer cylindrical surface of the member 11. r1he shoulder 16 and 20L are adapted to accommodate therebetween a preferably flexible Washer or gasket 23 as disclosed in Fig. 1.

Referring now to Fig. 3, there is shown a cylindrical cam-piece 24. Cam-piece 24 is provided with a longitudinal bore 25 of an identical cross-section throughout. Slots 26 and 26a formed parallel with said bore 25 are adapted to accommodate and to allow to slide therein the wings 21 and 21a. The upper annular' rim of cam-piece 24 is so formed as to have a point on its nia-jor surface 27 opposite the upwardly extending cam-nose 27 lic below said nose, and as to carry upwardly eX- tending cani-surfaces leading from said point to said nose, in such manner as to prow duce a suitable cam surface with which is adapted to cooperate the cam surface carried as aforesaid by cam-piece 11. In Fig. 3 certain portions of the cam-piece 24 are shown as being broken away in order to render more clear the presence of the slots 26 and 26a.

Referring now to Figs. 4 and 4, there is shown a member 28 including a plurality of cylindrical elements 29, 30 and 31, having therethrough from end to end thereof an axial passage of varied cross-section, said passage being threaded at its upper extremity to admit the adjusting screw 33, all as shown in Fig. 1. This passage (Fig. 1) includes a cylindrical bore 32, and a generally cylindrical valve-chamber 32, the said bore and valve chamber being oined by aV conical recess as shown. Near the lower lextremity of the portion 31 there may be provided a plurality of radial holes 32h to communicate above the valve-chamber 32a with the bore the annular space established between the dee pending reduced portion 33a of the screw 33 and the bore 32, with the valve-chamber 32a.

Considering now particularly Fig. 1,V the parts above described areshown assembled within the shell 5. A ball or spherical valve 35 is disclosed as occupying the valve-chamber 32, and as held loosely therein by a pin 36 and by the adjustment of the stud 33.

An expansile spring 37 is accommodated within the shell 5 between the plug and the member 28, thus forcing said member and the cam piece 24 against the cam piece 11.

The squared key-portion 19 of the member 17 projects through a complementary hole in the upper end-piece 8 and said member is further held in rigid relation with said eudpiece by the ornamental stud 37.

A similar stud 38 provides connecting and rotating means between the plug 5a and the lower end-piece 8a.

The operation of the above described embodiment of this invention, which should largely be obvious, is substantially as follows:

Let us assume that the leaf 6 (Fig. 1) is attached to a door-frame, and that the leaf 9 is attached to a swinging door. According to the locations of the parts shown in Fig. 1, the door is assumed to have been swung to and maintained in open position, the hinge-leaves lying in a single vertical plane and the parts being located as disclosed. A suitable amount of checking liquid, such as a proper' mixture of glycerin and alcohol, having been originally admitted to the interior of the shell 5, said liquid is now presumed to be wholly collected within the space 37a. The operation which opened the said door,V and thereby located the parts as aforesaid, was accomplished, as is desirable, without resistance, because in the doors closed position the cam-noses 14 and 27 were arranged one vertically above the other and consequently the campiece 24 was depressed below its illustrated location in Fig. 1 to shorten the height of the space 37a suiiiciently to locate some ofthe liquid above the valve 35. It should be remembered in this connection that the wings 21 and 21L turn fXedly with leaf 9 (the leaf whichis connected to the door), and that the parts arerso designed IIA n1,226,258 fr that with the leaf 9 arranged abutting or parallel with the leaf 6 the door is in closed position and wings 21 and 2la are through their cooperation with slots 26 and 26EL maintaining the cam-piece 24 in such a rotated location relatively of cam-piece 11 that said cam-noses are in abutment as aforesaid. So it will be seen that with the leaves 6 and 9 disposed as shown in Fig. 1, that is, with the door in open position, and with the campiece l24 driven by the spring 37 to overlap the cam-piece 11 as shown, upon the dooropening operation there was created a vacuum in the space 37a suilicient to draw the ball 35 away from the portion 33El of screw 33 and to allow the consequent suction to draw downwardly past said ball and without resistance the liquid theretoltore and normally located above the valve. But let the door now be released from its illustrated open position. The said door may be arranged to be forced closed by any suitable means associated therewith, such as an ordinary spring hinge (not here shown). The ensuing closing of the door (that is, the turning as one unit of meinber, 18 and cam-piece 24) causes the leaf 9 to move said cam-piece 24 relatively of the cam-piece 11, in turn to cause the camnoses 27 again to come into abutment with cam-nose 14, whereby the cam-piece 24 is forced to travel longitudinally of the wings 21 and 21a and consequently downwardly of shell 5. The liquid in the space 37a, being practically incompressible, is during this operation forced "to vpass through theball-valve established by the ball 35 and the chamber 35ZL and to pass through the annular space surrounding the portion 33n of the screw 33, thence through the radial holes 32, thence through the annular space 34, and thence into the upper interior ot shell 5. Immediately upon the flow of liquid commencing, the ball 35` tends to rise and `close communication between the chamber 32a and the bore 32, but is predeterminedly prevented from completely doing so and consequently predetermines the restriction of liquid through the parts as aforesaid, in accordance with the preliminary adjustment of screw 33.

In the construction just described, the cam-piece 24 is shown as not having the valve-chamber 32a formed in an integral portion thereof. the member 28 having been employed as disclosed to establish a series of tortumm or angularly offset passages leading upwardly from the valve-chamber, thereby to additionally barlile the contained liquid. And were said additional baflling of the fluid not contemplated, a single member in substitution for the member 28 and the cam-piece 34 could be readily employed, thereby attaining an added economy of construction, In Figs. 5, 6, 6 and 6l are dis closed two of the many possible such substitute structures capable of utilization. Thus in Fig. 5 is disclosed a unitary campiece 39, which, similarly to the joined campiece 24 and member 28, includes slots 26 and 26a, canrsurfaces 27 and 27, a bore 25, a cylindrical passage 32 with a lower Haring mouth, and a valve-chamber 32a, and has associated therewith a ball 35, a pin 36, and a screw 33 with a. depending portion 33a but this unitary cam-piece 39 additionally carries a plurality of radial and inclinedpassages 40` leading from the annular space`between the depending portion 33a of screw 33 and cylindrical passage 32 to the bore 2f. and in Eig. 6 there is disclosed another' type of unitary cam-piece 41, which, simila rly to the joined cam-piece 24 and member 28, includes slots 26 and 26a, cam-surfaces 27 and 27, a bore 25, a cylindrical passage 32 with a lower flaring mouth, and a valvechamber 32a, and has associated therewith a ball 35, a pin 36, anda screw 33 with a depending portion 33a; but the screw, as best disclosed in Fig. 6a, is bored at 42 and additionally kerfed as at 43. Fig. 6b shows for purposes or' illustrative disclosure a substitute form of screw 33 which could well. be employed in connection with unitary campiece 41, the screw being longitudinally slotted as at 44.

It will thus be seen that I have provided an embodiment of the invention capacitated to attain the objects of inconspicuity and extreme exibility of adjustment, compactness, inexpensiveness of manufacture, simplicity of construction, and reliability of operation.

I have illustrated preferred and satisfactory forms ott my invention, but it is obvious that changes may be made therein within the spiritand scope thereof as de iined in the appended claims.
